Abstract

Single quasicrystals Al72Ni12Co16 and Al72Pd19Mn9 alloys have been grown by the floating-zone method and Zn46Mg51Ho3 alloy by the Bridgman method. In these three systems, single quasicrystals with dimensions of the order of a centimeter have been successfully grown. X-ray diffraction and neutron diffraction show that these single quasi-crystals are as good as the best crystals. We therefore assert that quasicrystals are a metallic bulk matter with a degree of order equal to that of best crystals. By quenching the liquid, we observed flat solid-liquid interface perpendicular to the growth directions in Al-Ni-Co and Al-Pd-Mn alloys.
